Problems solved by technology

[0004] In order to solve the problem of insufficient heat dissipation of traditional high-power LED street lamp radiators and the inability to recycle the heat generated by LED street lamps during operation, the present invention provides a street lamp cooling device for driving a Stirling engine with waste heat, which can convert high-power LED The heat generated when the street lamp is working is converted into mechanical energy by the Stirling engine to provide power for the radiator fan, so that the radiator of the high-power LED street lamp is in a forced convection heat exchange environment, and the heat dissipation of the radiator of the high-power LED street lamp is improved, and the LED street lamp is realized. Waste heat recovery and utilization to achieve the purpose of "dissipating heat with heat"

Embodiment Construction

[0011] The present invention will be further described below in conjunction with specific embodiments. Such as figure 1 , figure 2 , a street lamp cooling device driven by waste heat Stirling engine, including LED street lamp beads 1, heat transfer medium 2, heat pipe radiator 3, heat dissipation fins 4 of heat pipe radiator, hot cylinder 5 of Stirling engine, heat-insulating and sealing piston 6. Cold cylinder 7 of Stirling engine, cooling fins 8 of Stirling engine, hinge mechanism 9 , eccentric hinge mechanism 10 , fan impeller 11 , piston 12 of cold cylinder.

[0012] When the LED street lamp bead 1 is working, a large amount of waste heat will be generated, and this part of waste heat will be transferred to the heating section of the heat pipe radiator 3 in the form of heat conduction, and then divided into two parts, which will be transferred to the heat of the Stirling engine through heat conduction. Cooling section of cylinder and heat pipe radiator 3. The Stirling ...

Abstract

The invention discloses a street lamp cooling device of a waste heat drive Stirling engine. Waste heat generated during work of a high-power LED street lamp is used for driving the Stirling engine soas to provide power for a fan impeller of a cooling fan of the Stirling engine, after the cooling fan of the Stirling engine works, heat emitting of a heat pipe radiator of the LED streetlamp is reinforced, and the aim of emitting heat through heat is achieved.

Description

technical field [0001] The invention relates to a street lamp cooling device for a Stirling engine driven by residual heat, belonging to the field of street lamp cooling. Background technique [0002] As the Ministry of Science and Technology's "Ten Cities Ten Thousand Lights Plan" enters the second phase, high-power LED lights have been widely used in street lighting. Compared with incandescent lamps used in traditional street lights, they have the advantages of low-carbon environmental protection, green energy saving, and long life. However, about 70%-80% of the electric energy input into high-power LED lamps is converted into heat and lost, and this part of heat has a high heat flux density. If this part of heat is not exported from high-power LED street lamp beads in time, it will affect The light output efficiency, and the thermal stress generated in the chip will destroy its internal structure. If this part of the heat is directly dissipated, there will be a problem of...
